What it does
GraphQL query formatter — pretty-print or minify operations. Handles queries, mutations, subscriptions, fragments, inline-fragments, directives, variables, block strings, comments.
Hand-written tokenizer (no graphql package) so the tool stays small. Toggle between pretty and minified; shows compression ratio after minify.
